Top 5 Safest Places to Scuba Dive

Scuba diving is obviously an activity that pumps up your adrenaline for it’s definitely risky. For the same reason, every dive must always be planned carefully. The topmost goal is to always be completely safe while enjoying underwater. In order to ensure that, there are certain factors to consider to tell if diving in a specific area on a specific day is okay. So before “diving” straight into the safest scuba diving places, let us first know the aspects which tell that a site is a safe place for diving. Through this, you won’t just know about amazing diving places but also their significance regarding safety.

Diving Conditions

These are the following conditions that need to be checked before deciding to scuba dive:

  • Weather

This is the most important thing to consider before scheduling a scuba diving stint. Why? It’s for the sole reason that it will dictate what happens above the water and below the water. On the other hand, this isn’t really as easy as checking accurate weather reports from the newspapers, television, radio, or the internet. It’s because weather changes from one place to another. Moreover, weather patterns in coastal regions often vary from that of the inland areas. Due to this, find a marine-oriented weather forecast that is catered for marine activities. Actually scuba diving or diving in general is really one of the outdoor activities that depend greatly on the weather.

Take note that a really heavy windy weather isn’t appropriate for diving. Why? This kind of weather will indeed make the ocean’s surface real rough. That will make the boat really unsteady which may then also result to your sea sickness. Furthermore, know that dive cruises, liveaboards, and deep ocean dives highly depend on the weather. On the other hand, experienced divers opt to go even in this kind of weather. It’s because for the thrill and challenge. So if you aren’t a professional diver or one who has tried diving for a reasonable number of times, just go when the weather is calm.

  • Tides

These are basically the changing water level in the ocean that results from the gravitational pull of the moon. The tidal condition is certainly a vital factor to take into consideration since tides either expose or conceal rocks that are near the water’s surface. During the high tide, more rocks are, of course, submerged. Conversely, during low tide, more rocks are exposed.

  • Swells

These are the result of small ripples, resulting from surface winds blowing along the ocean’s surface, getting bigger. They get larger because the said winds are getting stronger at the same time. Take note that swells affect the boat carrying the divers. Dive preparations, diving entries, and diving exits can definitely be affected even by the smallest of swells. So what more can larger swells do?

  • Surf

This is the result of waves reaching shallow water and then slowing down until they crash forward. The surf is something you must indeed think about if you are diving from the shore.

Take note that beaches with gentle slopes experience spilling breakers over a long distance. It can certainly be hard to pass through when waves are either large or close together. However, in beaches with steep slopes, expect that the surf can break close to the water’s edge. It’s advisable to avoid this because it’s really forceful, unless they are small enough to make a safe passage for you.

  • Surge

This is a back-and-forth movement of the water resulting from the passing overhead of the waves. Take note that strong surge will definitely restrict you from swimming. For this reason, you need to know how to adapt your swimming with the direction of the surge.

  • Currents

These are formed by winds, waves, tides, as well as the Earth’s rotation. In diving, there are three kinds of currents which are present near the shore that are certainly significant: longshore, rip, and tidal currents.

Longshore Currents are running parallel to the shore. Additionally, they are standing currents since they seldom change direction. Take note that you need to know the direction of this current for it can move you far from your diving entry and exit.

Rip Currents are running perpendicular to the shore. Additionally, they are transitory currents for they can definitely suddenly appear out of nowhere. Know that if you are surface swimming to a dive site, these currents can aid and move you closer towards there.

Tidal Currents results from the incoming and outgoing tides forcing water through a narrow passage. Additionally, they indeed change in direction and force a lot of times. Moreover, take note that these currents are absolutely forceful. Diving can be safely done when there are slack tidal currents or when tides are about to change direction.

  • Visibility

This is another important factor since scuba diving is all about seeing what’s underwater. Without a doubt, good visibility is a must. Bear in mind that there are many factors at play that certainly affects it. Those factors are weather, seasonal variation, water motion, bottom composition, as well as the time of the day. These affect the turbidity or how much particulate matter is in the water and the absorption or the amount of light that can penetrate underwater.

  • Water Temperature

The temperature of the body of water where you are diving should be on your mind as well. It would not be a good idea to dive without a wetsuit if the waters are cold. Wetsuits are designed to keep you warm with the rubber neoprene. In addition to this, they aren’t waterproof. On the other hand, you should choose a drysuit if the waters are extremely cold. Drysuits are also completely waterproof.

  • Upwellings

These occur when strong offshore winds blow out towards the sea. Moreover, they lower temperatures as well as increase visibility and nutrient content of the surface waters. Clearly, you have to take the chance when there are upwellings since they are good for diving.

  • Thermocline

This is a condition where the temperature in the water naturally decreases as you go deeper, but then there are just areas where there are indeed drastic changes. Take note that this frequently happens in fresh water lakes. However, it’s only occasional in oceans. You definitely need to be aware of this, so you know the right suit to wear for diving.

  • Critter

This refers to the living creatures in the waters you are planning to go dive into. This one is a 100% no-brainer since diving is all about exploring what the underneath has to offer. You definitely want to know what you are going to see down there.

  • Bottom Composition

This refers to the bottom features of the body of water you are diving into. Take note that these will dictate the things you will see underneath as well as the amount of visibility available. Furthermore, there are indeed different kinds of bottoms such as rocks, gravels, sans, silts, or mud.

  • Bottom Contour

This won’t just tell you about the kind of marine life that you will encounter down there, but the area’s depth range too. The favorable bottom contours for diving are those with steep or vertical bottoms. This is because they certainly have a huge marine life diversity for you to explore.

Safe Places to Scuba Dive

Another one of the safe spots to scuba dive is this. This popular diving site is actually a 120 meter long United States Army cargo ship. Back in January 1942, it left the coast of Australia to go to the Philippines and deliver railway parts and rubber. On January 11, 1942, when it reached the area between the Lombok and Bali islands, it was torpedoed by a Japanese submarine. There was definitely an attempt to tow it to Singaraja in Bali, but it was indeed sinking rapidly. Then it was beached halfway through in Tulamben. After that, the ship was just left there until Mount Agung erupted which made it to slide into the water. Nowadays, it’s already at a depth of around 7 to 35 meters.

Take note that diving is possible at any time of the year. Additionally, the waters here are consistently warm too. You can do muck diving, night diving, as well as wreck diving here. For photographers, prepare to have magnificent wide-angle shots of the marine biodiversity down there:
